Background

The Carvel State Office Building presents a unique opportunity to implement both larger scale energy conservation measures (ECMs) such has heavy mechanical systems alongside standard water saving and lighting measures.

By using an energy services company (ESCO), the State is confident that Carvel will be able to generate guaranteed savings, serving as an ideal showcase facility. The project is expected to result in savings of 7,545,904 site kBtu per year (equivalent to 21,890,638 source kBtu) and 26% of the building’s baseline energy consumption. In addition, the expected annual cost savings are $225,000.

The construction phase of the performance contract began in May 2012 and is anticipated to last through March 2013. As such, this project will focus first on implementing low-/no-cost energy ECMs beginning in November 2012 before introducing more comprehensive measures.

Heat pump replacement of 613 original perimeter pumps with high efficiency equivalents. Audit of the facility found 40% of the heat pumps were not fully operational at project baseline: Savings $30,652

Roof-mounted 10kW photovoltaic system, expanding existing system for a total of 20kW: Savings $1,517

Water Conservation to include the installation of 55 bathroom aerators: Savings $2,279
